Herbert Marshall McLuhan CC (July 21, 1911 - December 31, 1980) was a Canadian educator, philosopher, and scholar — a professor of English literature, a literary critic, and a communications theorist. McLuhan's work is viewed as one of the cornerstones of the study of media theory. He is known for coining the expressions "the medium is the message" and the "global village".

McLuhan was a fixture in media discourse from the late 1960s to his death and he continues to be an influential and controversial figure. During his lifetime and afterward, McLuhan heavily influenced cultural critics, thinkers, and media theorists such as Neil Postman, Camille Paglia, Timothy Leary, William Irwin Thompson, Paul Levinson, Douglas Rushkoff, Jaron Lanier, and French philosopher Jean Baudrillard, as well as political leaders such as Pierre Elliott Trudeau and Jerry Brown. When asked in the 70s for a way to sedate violences in Angola, he suggested a massive spread of TV devices. McLuhan was named as the "patron saint" of Wired Magazine and a quote of his appeared on the masthead for the first ten years of its publication.
